HIS iClear "noise reduction" PCI card doesn't really do much of anything

Say "Hi" to the HIS iClear "noise reduction" card, a peripheral that snaps into your computer's PCIe socket, just like a video card. What does it do? It is not clear. Dan Rutter investigates:

According to the iClear Card’s product page on the HIS site, it, and I quote verbatim, “is HIS latest solution to video card noise reduction. It has an excellent implement of state-of-the-art design and technology and give you a better gaming experience by reducing the distortion and noise generated from graphic card. It reduces the noise distortion generated from high-end graphic card (from both Radeon and GeForce) or TV tuner card, which provide up to 10% increase performance on Signal-to-Noise Ratio.”
